1. Introduction
The ARO Controller is capable of controlling upto two Electronic Interface Air Operated diaphragm pumps
independently or simultaneously. Each of the two pumps can be actuated in any of three modes: Manu-
al, Batch and Proportional each with specic process control capabilities. It can also output analog signals
representative of the speed of each of the pumps that can be used in other parts of the process for greater
automation possibilities.
The ARO Controller can also accept external signals, such as from uid levels, push buttons, analog sensors,
or even PLC signals, to automate pump start and stop per pre-programmed levels or specic control logic.
The ARO Controller can also detect abnormal or undesirable conditions and react to them, by either trigger-
ing an external alarm, stopping the pump or both. For emergency situations, it can also accept an Emergency
Stop signal that will stop both pumps immediately.
It features a durable membrane user interface with an LCD screen that makes interacting with the unit very
easy, and its programming is based on a very intuitive menu logic. Its plastic housing is rated NEMA 4X for
hermeticity.
The version 2.0 software for the ARO controller can control a ow meter which measures the ow inde-
pendently or simultaneously. The function of the ow meter is designed to connect with the standard PD
pump without an EOS or the solenoid input. The ARO Controller is capable of connecting/controlling two
ow meters.
NOTE: The ARO controller can operate with one pump or two pumps simultaneously, with one ow meter
or two ow meters simultaneously, but will not operate with one pump and one ow meter simultaneously.
2. Setup
The Setup menu features a number of options to modify the controller’s general behaviour (General Setup),
program specic pump run modes (Run Setup), and specify general pump behaviours (Pump Setup).
The Setup menu is password protected. To exit the password-protected menu, press “NAVIGATE TO
PREVIOUS” enough times to exit the Setup menu; press “NAVIGATE TO HOME”, or leave the controller
unattended. After 10 minutes of no key strokes on the keyboard the controller will automatically exit the
password protected menu. If the screen shows a pump that is running, the screen will change to the
equivalent running mode screen outside the password-protected menu. In all other cases, the controller will
exit to the Home screen.
On the Home screen, select the “Setup” and press ENTER.
On the “Password” screen, press ENTER and then type the password: 27632.
Press ENTER again.
When the correct password is entered the Setup screen is displayed.
If a wrong password is typed, an alert message is displayed. Select “Password” and
press ENTER to type the correct password.
NOTE: If the user forgets the password, the software must be installed again. Refer
to section 4.
